The .NET Collection Interface Interactive Guide (CIIG) is a project launched for learning all collection interfaces that are introduced in .NET Standard. The project is designed as simple as possible to help .NET developers learn how they are different and what they support.

The project provides two modes: Questionnaire mode and Check List mode. In Questionnaire mode, the project chooses a collection interface from the pool based on the user’s answers to a series of questions. In Check List mode, the project lists all available interfaces according to the user’s feature check list.

The project is still very young. We hope developers find the project helpful.
